    “Assuming” these are genuine Samsung 18650’s

    There’s no actual Samsung branded markings on these batteries as supplied (or shown in the photos) so it’s debatable if they’re legitimate. The protection was already triggered on these when they arrived so charging them was fiddly as a result and would indicate they’ve likely been in storage for some time and may have suffered as a result. Each battery weighs in at around 42 grams - consistent with a quality 2500mAh battery. Time will tell if they handle consistent discharge and recharge cycling.

  • Most critical review

    Not the high expectations I thought they would be!

    Not sure they are the right batteries for me, so dont want to give them a bad rap if this is the case. I have Wismec Releaux 3 and it seems to drain these batteries just as quickly it did with my old ones which were a couple of years old. Probably get 12-14 hours usage from three batteries, which maybe people will say is ok for the machine.

  • Happy to have my old drill as good as new with Samsung INR18650-25Rs

    I guess we are all used to inflated figures for the capacity of rechargeable batteries. With these Samsungs, you know that they will meet the specs published in the datasheet. They are rated at 2.5Ah, 20A continuous and 100A momentary which makes them ideal for replacing the ancient NiCds in one of my drills. They are not protected which means that they do not have an internal battery management system, but you can add this with something like the Silicon Chip Battery Lifesaver.

  • Great batteries

    Tested capacity on Littokala charger, I got 2441 mAh & 2438 mAh. Pass the minimum mAh standard. High current usage, work well on Noctigon M43 LED Torchlight. Posted in plastic case. All good!

  • Doesn't produce required power as advertised

    I don't know if these are knock off batteries but they don't output the required power. I'm getting low current warnings at 65% charge. Not recommended.

  • Work fine in wife's grass/hedge shears

    After soldering these batteries inside my wife's grass/hedge shears, and charging them with the shears' charger, the shears worked fine and ran for a good time. No complaints!

  • Buy and try with confidence.

    Five stars should be only gauged after several usages and over an extended of few months or years. However the product itself look from solid quality made material. So my rating of 5 stars has little value.

  • All good

    So far the batteries have performed well with constant use and wouldn't hesitate to buy again.
